The first robotic vehicles in the development stage are now test-driving autonomously at two plant sites, transporting material for brake production.
Technology company Continental has developed a state-of-the-art, autonomous transport vehicle to further increase the efficiency of its own production. In the production of brake systems, for example, autonomous Automated Guided Vehicles (aAGV) developed and constructed in-house can transport heavy loads of over a ton.
Continental says the technological solution is an integral part of its Industry 4.0 strategy. The aim is to optimise the entire value chain using digitised processes and data flows with high transparency and predictability, short throughput times, low inventories, and high flexibility.
Continental sees great potential in the development of its own aAGV. This applies to Industry 4.0 as well as for business areas such as logistics and many other fields of application in which the autonomous transportation of goods can be used to increase efficiency. In the meantime, aAGV are demonstrating their performance and carrying capacity day after day at Continental locations in Zvolen (Slovakia) and Frankfurt am Main (Germany). The first robotic vehicles in the development stage are now test-driving autonomously there between start and destination, transporting material for brake production.
The aAGV align themselves to the correct direction and flexibly avoid obstacles. This in-house development was made possible by, among other things, a technology transfer from the passenger car sector. The expertise from highly-reliable automotive-grade environmental sensors such as radar, camera, ultrasonic, and Lidar, as well as sensor fusion and the environment model, was a key component in the development of the aAGV.
Optimization of material transport
Automated guided vehicles play an important role in the material flow in a digitised factory: They reduce manual activities such as driving forklift trucks, speeding up transport, making it clear exactly what goods are available and where at all times, and making processes more predictable in general. At the moment the only mobile transport robots on the market are those that predominantly do not drive autonomously and only move on fixed routes between programmed start and target locations. Any change requires complex reprogramming, time and additional costs for modifications to the site.
During the design, production, and assembly of the aAGV, the project team was able to build on the experience gained in the automotive sector. Technologies such as sensors from the passenger car sector were combined with control technology, mechatronics, and conventional mechanical engineering. Only the electric drive train and the software for controlling the vehicle are based on the technologies available on the market. The aim is for the aAGV to be available worldwide as a basic technology for use in production at Continental.
In order to design the aAGV to be particularly maintenance-friendly at the development stage, the development team is using its practical experience from industrial production. Of course, the findings from ongoing test operation in real-life conditions also flow into the planned production version in response to this. Volume production is to begin after the test phase. It is also planned to offer the system outside Continental at a later point in time.
